SPECIFICATION forming part of Letters Patent N0. 738,073, dated September 1, 1903.

Application filed January 13, 1903. Serial No. 138,869. (No model.)

To all whom it may concern:

Be it known that I, MARTIN SCHE LL, a eiti zen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented new and useful Improvements in Cameras, of which the following is a specification.

My invention relates to new and useful improvements in cameras, but is more especially an improvement upon the device shown and described in my application filed July 15,1902, Serial No. 115,730.

One ob j ect is to provide means whereby the front plate of the camera may be locked in any desired position when the bellows is extended from the case.

A further object isto employ means whereby the device may be quickly adjusted vertically or laterally to obtain the desired focus.

lVith the above and other objects in view the invention consists in the further novel construction and combination of parts hereinafter more fully described and claimed, and illustrated in the accompanying` drawings, showing the preferred form of my invention, and in which- Figure 1 is a perspective view of a camera embodying my improvements. Fig. 2 is a plan view thereof. Fig. 3 is a rear elevation of the front plate of the camera detached, and Fig. 4 is a section on line .r a; of Fig. 8.

Referring to the figures by numerals of reference, 1 is a camera-casing preferably so constructed as to permit the front 2 thereof to swing downward to form the base of the front plate This plate is provided at its lower edge with forwardly-extending feet 4, preferably T-shaped in cross section and adapted to travel within guides 5, larranged longitudinally upon the innerface of the front 2, near the opposite sides thereof. An inwardly-turned flange G is formed upon the lower edge of the front plate 3, and the ends thereof are adapted to overlap the inner edges of downwardly-extending arms 7, formed at the ends of a slide S. This slide is guided between the inner surface of front plate o and the ends of flange G, and arms 7 are adapted to be normally held in contact with the guides 5 by means of a bowspring 9, which bears upon the upper edge of the slide S and is secured at a point intermediate its ends.

If desired, notches 5fL may be formed in the guides at suitable points to receive the arm 7 when they are brought into position thereabove. I preferably provide one set of notches which are adapted to receive the arms 7 when the objective is brought into universal focus. A bracket 10 is secured upon the front surface of plate 3, near the lower edge thereof, and is provided with a forwardly-extending arm 11. Pivoted within this bracket is a lever 12, the inner end of which projects through a slot 13 in plate and engages an aperture le, formed Within slide 8. It will therefore be understood that when lever 12 is pressed downward toward the arm 11 slide 8 will be raised, and thereby draw the arms 7 out of contact with the guides 5. Spring 9 will at the same time be contracted, and as soon as the lever 12 is released this spring will return the parts to normal position.

A preferably rectangular aperture 15 is` formed within the plate 23, and the objective 1G of the camera as well as the finder 17 thereof are adapted to extend therethroughl The objective and finder are mounted upon a slide 1S, arranged in rear of plate 3 and having side iianges 19, from which project downwardly-extending arms 20. A flange 21 is also formed at the lower edge of the slide 18, and this flange, as well as the side flanges 19, incloses the forward end of a bellows 22, adapted to be secured to slide 1S in any suitable manner.

A rack 23 is secured to the rear face of plate 3, near each side thereof and adjacent to its lower end, and each rack is engaged by a gear 2l, mounted upon a shaft 25, which is journaled in arms 20,before referred to, and serves to guide them when lateral movement is imparted to slide 18. slidably mounted in slots 26, formed longitudinally within side flanges 27 of the front plate A milled head 2S is secured to shaft 25, at one end thereof, and by means of the The ends of this shaft are same said shaft may be readily turned and IOO from and through the slot 32 in the adjacent ange 27. This stem, as well as the springarm 30, serves to hold slide lS in position in rear of plate 3, and the spring-arm 30 also clamps said slide upon the plate E3 and supports it in any position to which it may be moved vertically. A slotted bracket 33 is secured upon the slotted flange 27 and extends over the slot 32 before referred to. Anut 34 is arranged between said flange 27 and bracket 33 and is mounted on stem 3l. It is therefore obvious that when said nut is turned upon the stem lateral movement of the slide 18 and the objective and finder thereon may be obtained.

By use of the mechanism herein employed it will be understood that it is unnecessary to employ a laterally-movable front plate 3, and as the head 28 and nut 34 are located at convenient points the objective and the nder may be quickly and accurately moved to desired positions. ployed for securinthe front plate in adjusted position upon the guides is extremely simple and effective and can be promptly released by means of the lever projecting from the base of the front plate.

In the foregoing` description I have shown the preferred form of my invention, but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing any of the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the spirit of the invention.

Having thus described the invention, what is claimed as new isl. In a camera, th e combination with a front plate having an inwardlyextending ange, and guides for said plate; of aslide mounted upon one face of the plate, arms thereto slidably mounted between the ends of the flange and said plate, a spring bearing upon the slide and adapted to hold the arms normally in contact with the guides, and a forwardly-projecting lever upon the plate and engaging said slide, whereby the slide may be lifted and the front plate moved upon its guides simultaneously.

2. In a camera, the combination with a front plate having an aperture therein, guides for said plate, and means for locking the plate upon the guides; of a slide mounted upon the plate in rear of the aperture and adapted to be secured to the bellows of a camera, and means for imparting vertical and lateral movement to said slide, independently of the plate.

3. In a camera, the combination with a front plate having an aperture therein, guides therefor, and means for securing said plate to the guides 5 of a slide mounted upon said plate in rear of the aperture and adapted to be secured to a bellows, a threaded stem extending laterally from said slide, means for imparting longitudinal movement to said stem and adjusting the slide laterally in relation to the plate, and a guide for said slide.

The locking mechanism emp 4. In a camera, the combination with a front plate having an aperture therein, and means for locking said plate in adjusted position; of a slide mounted in rear of said aperture, a shaft journaled upon the plate and adapted to guide the slide when moved laterally, a spring-arm upon the plate and bearing upon the slide, and means for imparting vertical or lateral movement to said slide independently of the plate. j

5. In a camera, the combination with a front plate having an aperture therein, and means for locking said plate in adjusted position; of a slide upon the plate in rear of the aperture, said slide being adapted to be secured to a bellows, a rack upon the plate, a shaft engaging the slide and adapted to guide the same laterally, a gear upon the shaft meshing with the rack, whereby the slide may be moved independently of the plate, and retaining means for holding said slide in adjusted position.

G. In a camera, the combination with a front plate having` an aperture therein, and means for locking said plate in adj usted position; of a slide upon the plate and extending across said aperture, arms to the slide, a shaft journaled within the arms, a gear thereon, a rack upon the plate and engaged by the gear, whereby when the shaft is turned said slide may be adjusted independently of the plate, and a spring-arm upon the plate and contacting with the slide, whereby said slide may be held in adjusted position.

7. In a camera, the combination with a front plate having an aperture therein, and means for locking said plate in adjusted position; of a slide extending across said aperture and adapted to be secured to a bellows, a threaded stem secured to the slide, a revoluble nut upon the stem, means for preventing longitudinal movement of the nut, whereby when said nut is turned movement is imparted to the stem and slide.

8. In a camera, the combination with afront plate having an aperture therein, and means for locking said plate in adjusted position; of a slide extending across the aperture and adapted to be secured to the bellows, racks upon the plate, arms extending from the slide, a shaft journaled in said arm, gears therein meshing with the racks, 4whereby when said shaft is revolved, the slide may be moved independently of the plate, a spring-arm bearing upon the slide and adapted to retain it in adjusted position, a threaded stem projecting from the slide, a revoluble nut thereon, and means for preventing longitudinal movement of the nut whereby when said nut is revolved motion is imparted to the stem and slide.

In testimony whereof I affix my signature in presence of two witnesses.
